Why are liquid silicone products not smooth?

There may be several reasons why liquid silicone products may not be smooth:

1. Poor quality of silicone raw materials: If the quality of silicone raw materials used is not good, it may lead to uneven surface of the product.

2. Improper manufacturing process: During the manufacturing process, if the process operation is improper, such as uneven surface of the mold or bubbles appearing during the injection process, it can lead to an unsmooth surface of the product.

3. Uneven curing of silicone: During the curing process of silicone, if the curing is not uniform, it may result in an uneven surface.

4. Improper use of molds: If the molds are used too many times or improperly, it may lead to wear or deformation of the mold surface, thereby affecting the smoothness of the product surface.

5. Unreasonable silicone composition ratio: The composition ratio of silicone products has a certain impact on their surface smoothness. If the ratio is not reasonable, it may lead to an uneven surface of the product.

In short, the occurrence of unevenness in liquid silicone products may be caused by various factors such as the quality of silicone raw materials, manufacturing process, silicone curing, mold use, and silicone composition ratio.
